[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] To address the shortcomings of existing charging pile front doors in terms of structural strength, cable retraction performance, and brand identification, this embodiment discloses a novel charging pile front door, with the overall structure set as follows: Figure 1 and Figure 2 As shown, it includes a front door body 1, on which a cable retracting device is integrated. The sheet metal is designed with an inward bending to enhance structural strength. At the same time, a dedicated flat enlarged area is reserved for silkscreening the company logo and related product information. The layout of other functional components is also optimized, thus obtaining a new type of charging pile front door that integrates structural reinforcement, brand display, and charging gun cable retracting, which is suitable for various home and commercial charging pile devices.

[0027] First, such as Figure 3 As shown, the supporting structure of the front door of this new type of charging pile includes a front door body 1, a housing frame 2, and a cable baffle 3. The front door body 1, housing frame 2, and cable baffle 3 are all made of high-strength sheet metal materials, such as high-quality cold-rolled steel plates or aluminum alloys with a thickness of 1.5mm-3mm. These two materials have good strength and toughness, which can meet the stress requirements during the charging gun cable retraction process. Meanwhile, to improve the corrosion resistance of the sheet metal structure, the surface of the cold-rolled steel plate or stainless steel plate must be coated with an anti-corrosion coating. The sheet metal surface undergoes pretreatment, such as grinding and rust removal, and then surface protection is achieved through a spraying process. Corrosion-resistant and weather-resistant paints can be selected for spraying, and the color can be customized according to the company's brand image or usage scenario requirements. The anti-corrosion coating effectively resists external environmental erosion and extends the service life of the sheet metal structure.

[0028] The front door body 1 is cut into a suitable shape based on the charging pile. The hollow internal frame 2 is welded and fixed on the front side of the front door body 1. Then, the cable baffle 3 is welded and fixed on the front end of the frame 2. The area of ​​the cable baffle 3 is larger than the area of ​​the front side of the frame 2. The frame 2 forms a cable storage area around its perimeter to wrap and store the charging cable on the frame 2.

[0029] To enhance structural strength, the front door body 1 and the baffle plate 3 are both formed with inward bending at the edges using an inward bending process. The bending angle of the inward bending edge is 90-135°. During the bending process, the bending angle and precision must be strictly controlled to ensure that the structure after inward bending meets the design strength and has sufficient strength.

[0030] The inward-folding bends serve as reinforcing ribs, distributed along the length and width of the front door body 1 and the baffle plate 3, forming a stable support with the sheet metal main body planar structure. This design can enhance the structural strength without excessively increasing the difficulty of sheet metal processing.

[0031] Furthermore, the bend of the inward-folding edge adopts a rounded transition, and the radius of the rounded transition is determined according to the thickness of the sheet metal. This effectively disperses the stress at the bend and avoids cracking due to stress concentration during long-term use.

[0032] Furthermore, all corners of the front door body 1, the cabin frame 2, and the cable baffle 3 are rounded with a radius of 2mm-5mm to prevent scratches to operators or charging gun cables during use.

[0033] Therefore, regarding the structural design of the aforementioned cable reel, during the cable reeling process, the pulling of the cable will generate continuous tension and torque on the sheet metal of the cable reel; the inward bending edge, as a reinforcing rib, forms a three-dimensional frame with the planar part of the sheet metal body, forming a reinforced force support; furthermore, the inward bending angle (90-135°) and the arc transition design further optimize the force transmission path, avoiding deformation or breakage due to stress concentration, thereby ensuring cable reeling stability and extending the service life of the cable reel.

[0034] Furthermore, by setting the wire baffle 3, the front door of this new type of charging pile has an enlarged flat area. This flat area serves as the screen printing area 8. Since it is not obstructed and is located in a position that is easy to observe, it can be used to screen print the company logo and related product information.

[0035] The area of ​​silkscreen area 8 shall not be less than 50cm² 2 It is large enough to accommodate standard-sized company logos, product models, parameters, and other information. The surface of the screen printing area is polished to ensure that the surface roughness Ra is no greater than 1.6μm, providing a good adhesion base for screen printing and ensuring that the screen-printed pattern is clear, firm, and not easy to fall off.

[0036] Furthermore, such as Figure 4 and Figure 5 As shown, a drainage hole 20 is provided on the bottom inward folded edge of the cable baffle 3. The drainage hole 20 serves as a drainage window, and its shape can be selected as rectangular or circular according to actual needs. Its area is 1 / 5 to 1 / 3 of the area of ​​the bottom inward folded edge to ensure drainage efficiency. By setting the drainage hole at the lowest point of the sheet metal of the cable baffle 3, water that may remain during use (such as rainwater, cleaning water, etc.) can be guided out, effectively reducing problems such as sheet metal corrosion and internal component dampness caused by water accumulation, and further improving the reliability and safety of the front door of this charging pile in humid environments.

[0037] Therefore, the novel charging pile front door disclosed in this embodiment has the following advantages: 1) The layout includes a cable management device, which can effectively solve the problems of inconvenient storage of charging cables in existing charging piles, such as tangling and dragging on the ground, which not only affect the aesthetics but also pose safety hazards. 2) The sheet metal of the front door body and the cable tray is bent at a specific angle and formed by a specific process to form an inwardly bent edge with a reinforced structure. This enhances the overall structural strength and resistance to deformation, effectively copes with the tension and torque generated during the charging gun cable winding process, and extends the service life of the product.

[0038] 3) The oil reservoir with sheet metal baffle plate increases the effective area while ensuring stability, thus making it possible to set up a screen printing area. The screen printing area is used to screen print the formula logo and related product information, which not only improves the brand recognition of the product, but also avoids the cost increase and structural complexity caused by setting up additional display components.

[0039] 4) The bottom of the baffle plate has a cleverly designed drainage hole structure, which can guide residual moisture (such as rainwater, cleaning water, etc.) to be discharged smoothly, further improving the reliability and safety of the product in humid environments.
